Re: Cant download from the store
@Lola38103 One possible problem is if your browser is set to block pop-ups, so either whitelist this site or use a different browser. I always use Firefox (in both Windows and macOS) to download from the store, and it's usually fine.
Another potential issue is trying to download a large amount of content at once. Worlds should be downloaded separately and one at a time; for everything else, the launcher is usually stable with around six items but not more.
